SJPECIFIGATION forming part of Letters Patent No. 400,878, dated April 2, 1889.

Application filed June 20, 1888. Serial No. 277,666. (No model.)

To all whom it may concern:

Be it known that I, DAVID K. S ONE, of Bloomingdale, Van Buren county, in the State of Michigan, have invented an Improvement in Thill-Oouplings, of which the following is a specification.

The invention will be first described, and then pointed out in the claim.

Figure 1 of the drawings is a plan View; Fig. 2, a side elevation; Fig. 3, a longitudinal vertical section, and Fig. 4 a vertical cross-section.

In the drawings, A represents the front axle of a vehicle, B the yoke secured to cross-bars O by nuts 13, and O the head in which the thill is pivoted. The rubber D is concaved at d, and fits in the rabbet c of the head. On the thill end is formed an eye, E, which fits on a pivot, F, made fast at one end to the head and having the other end free. side of the head 0' is a hinged latch, G, which has a hole, g, through which works the free end of the pivot F.

On one H is a spring which passes through the latch-hole g, while the latch is locked by means of the corresponding shoulders, g 71 on the latch and spring.

Having thus described all that is necessary to a full understanding of my invention, what I claim as new, and desire to protect by Letters Patent, is

A thill-coupling consisting of the eye E on the thill, the head O, carrying the fixed pivot F in its rabbet c, a hinged side latch, G, having pivot-hole g and shoulders g a spring, H, having shoulders k and the cross-barred yoke B O, as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID K. STONE.
